Lists of objects

[cinefactus]

How general is the rule that Latin either separates the objects with et, or uses none at all? In addition to these Caesar seems to be quite happy to have x, y, zque.

praetereā magnum numerum ex Thessaliā Boeōtiā Achāiā Ēpīrōque supplēmentī nōmine in legiōnēs distribuerat
sagittāriōs Crētā, Lacedaemone, ex Pontō atque Syriā reliquīsque cīvitātibus iii mīlia numerō habēbat
Frūmentī vim maximam ex Thessaliā Asiā Aegyptō Crēta Cȳrēnīs reliquīsque regiōnibus comparāverat

 

[Pacifica]

All three ways you've mentioned are very usual. What's unusual in classical Latin is to use et between the last two items only.

 

[cinefactus]

Ah, I had mis-extrapolated the et rule to que.
